Answer:
[tex]r^{m-n}[/tex]
Step-by-step explanation:
We have been given an expression [tex]r^m\div r^n[/tex]. We are asked to find equivalent expression to our given expression.
First of all, we will write our given division problem as a fraction:
[tex]\frac{r^m}{r^n}[/tex]
Using exponent property [tex]\frac{a^b}{a^c}=a^{b-c}[/tex], we can rewrite our given expression as:
[tex]\frac{r^m}{r^n}=r^{m-n}[/tex]
Therefore, the expression [tex]r^{m-n}[/tex] is equivalent to our given expression.
